Starter Motor Function Check

Model: Ford Transit MK 7 - Years 2006-2014
Part: Starter motor

Once the starter motor is disassembled, checking its operation on the bench is very simple: just secure it in a vice and have a charged battery available to power it. Connect the earth to the motor casing or the vice, and with the positive clamp, bridge the fixed positive terminal and the +50 terminal: you will see the pinion extend and then rotate. If you notice that the extension and/or rotation of the pinion are a bit too slow, it is advisable to disassemble the motor to inspect the wear condition of the brushes and commutator: in this case, the brushes are completely worn; it is still possible to purchase this type of spare part for DIY refurbishment. In addition to replacing the brushes, it is advisable to clean the commutator, performing the so-called undercutting (cleaning between the segments and turning). Once the motor is reassembled, repeat the operation test: you will certainly notice a more responsive and explosive reaction.
